Song Yuxuan's parents eloped to Jiangcheng. Her father died of lung cancer not long after she was born, and her mother was killed in a car accident while taking her to the college entrance exam. Her mother's family brought her back to the Song family, and she lost touch with everyone from her former life. Drawn without reason into the Song family's struggle for power, Song Yuxuan was ground down into a numb person. Later, Gu Liu found her, cleared up the misunderstandings from the past, rescued her from the conflict, and cured her illness. The two fell in love.
"My name is Song Yuxuan. The 'Yu' means surplus."
"My name is Gu Liu. The 'Liu' means to stay."
Actually, 'Yu' can also mean something left behind. I mean, you aren't surplus at all. You're a beautiful memory that remains with me.
